T1 designates u vcvl'tim mmf, hmrimg; @u Mn ggtudina mening t.. und pmvidm im 'www oud with n pvut, S, which is smppd in n mit which extend lpusiste sides o'r the mast and provided at opposite sides with longitudinal grooves or Ways 25, 'which receive horizontal guide llanges 26, which are carried by the mast and inwardly from opposite sides of the Opening 2, as' clearly shown in Fig. -l of the drawin s. The shiftable beam is supported by a b ook 1, secured in the opening 2 and arranged beneath the shiftable beam, as clearly shown in Figs. 1 and 2, and the. beam and the iding and supporting means may be provi ed, if desired, with any suitable antifriction devices for enabling the beam to slide frietionlessl f. The grooves are open at one end to enable the. beam to be readi y laced in and removed from the standar and a suitable stop 241 is provided for reventrng the beam from accidentally leaving the guidelanges of the mast. The beam 1s provided at its upper face with a rack-bar 27, provided at its u per face with teeth, which mesh the teeth o a s ur-pinion 28, located above the shiftable oeam 'and mounted' on a short shaft 29, journaled in Suitable bearings 3() of the mast. The bearings 3G are located at opposite sides of the opening 2, and the shaft '29, which extends laterally from one side of the mast, also carries a sproeket-n'f'heel3l,receiving as rocketchain 32, which extends downwart ly to a sprocket-wheel The sprocketerheel 33 is ke ed or otherwise Secured to an operating-s aft 34, journaled in suitable bearings 35 of the mast and carrying a ratchet-wheel 36, which is preferably in the form of a spur gear and which is. engaged by a pawl or dog 37 of a lever 3?., The lever 38 is pivoted at its inner end Si'iand is located above, so that the pawl or dog is retained in engagement with the spur'gear by gravity. The. spur-gear is looked by the pawl or dog against rotation in Either direction, so that there is no liability of the s 'ftable load-carrying beam moving either inward or backward. A'ny other suitable meuns, however, may be employed lor loeliinir the benin in its adjustment. When the o lmating-slaaft, which is provided at. one end y ith a crank-handle 4U, is rotated, mo tion lis communicated from tho si'roclielgearing to the spur-pinion ".28, and tlie shiftablsi load-carrying beam is moved inward or outlward, according to the direction in which the' pinion is rotated.

The derrick is provided with hoisting ilelohanism consisting 'of a flexible connecytio/'n 41, which is preferably in the lor'm ol a ,chain and which passes over a guide-pulley /42 ofthe mast and op )osito guido-pulleys 43 l and 44 ofy the shilta )le load-carrying beam.

6o The pulley 42 is located above the mast., in

the opening 2 thoryol', and carries lho ilexi- 'ble ooiincction cloni of tho gearing l'or operN i ating t icslnl'table loa l-carryingboain. 'l`h l pulley.` 43 and 44 are mounted in sultablc "35 openings adjacent to the ends oi the. sluiteicfgeei able load-carrying beam, and the chain 4l extends downwarda from the pulley -ll to a windingshal't i5, journaled in suitable bear ings 46 and preferably provided with a drum to receive one end of the llexible connection, which is suitably secured to the drum. The winding-shaft, which extends laterally from one side ol' the mast, carries a spur-gear i8, which meshes with a's nir-pinion 4) of a counter-shaft 5l). journaled in suitable bearings 5l of 4the mast. The counteI-shaft is provil ed with a. suitable crank-lnilnlle 5;. bv means of which tht` winding-shaft is rotator( The spur-gear -lS is engaged by a. pivotod pawl or dog 53, which locks the hoisting mechanism at any adjustment. The pawl or dog 53 extends upwardly trom a pivot 54, and is provided with a. dowuwardlywxtending handle 55, by means ol' which the pawl or dog 53 is readily moved into and out ol engagement with the spur-gear lo. The other end of the chain depends lrom the pulley 43, which is located at the lront or outer end of the shiltable load-carrying beam, and this end oll the chain is prorided witn a plurality of branches 5U. having terminal hooks 57, adapted 1o engage eyes 5H ol' a hay-rack 5), as shown in dotted lines in Fig. l ofthe drawings; but the llexibhl connection may be provided with any other suitable means for enabling it to be conveniently connected lo the load to bc handled. 'llu` hoisting mcfanism is adapted to be connected lo the hay-rack or wagon-bed, and it will enable tile same to be readily lil'tcd either l'rom the ground or 1from the running-gear to place a hay-rack or wagon-bed on ils running-gear or to remove it therefrom. When a hayrack or ii'agon-bed is liftcd l'rom its runninggear, tht7x dcrrick is adupted to be. rotat'edto .swing its load from over the running-gear, and the shil'table boum is :idnpled to bo moved either inwardly or outwardly lo deposit the hay-rack or aired point. rThis will enabh` the hay-raul( or wagon-bed to be quickly picked from the ground, hoisted to the desired elevation, and swung around over its running-geni and deposited thereon. 'l`ln` particular zirrangement ofthe llexible connection which has its Vside portions depending l'rom the slxil'tablc beam at opposite sides oll the mast enables the load-carrying beam to be shifted o1' moved inward'or outwznd without all'ecting the hoisting mechanism or changing the clevnlion ollhe load. chain is carried :may from the mast by tho shifting ol' the limiti-carrying boum, the opposite sidel of the chain is moved inwardly lo compensate lor the outward .movement ollhc side which is carried away l'rom the unisi..

The dcrricl: may be advanlngcously employed in l'arnnbulchi-ry and will enable an animal 'lo be readily hoisted clear oi the l ground for slaughteringcleaning, or otherwagon-bcd at the (lc-- When one sidc ol' the eimer p be readily deposited iineveliiele.
